UMBILICAL LIGATURE.

Application filed October 2, 1924. Serial No. 741,102.

To all whom it may concern:

Be it known that I, ARTHUR H. HAUBER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and use ful Improvements in Umbilical Ligatures, ofwhich the following is a specification.

My invention pertains to ligatures or clamps especially, but notrestrictedly, adapted for satisfactory and eiiicient employment onumbilical cords, whereby to effectively compress, constrict and closethe blood vessels thereof.

One object of the present invention is to provide a ligature of thischaracter which will produce absolute and complete hemostasis byflattening and transversely squeezing the blood vessels of the cordwithout possibility of puckering, folding or creasing them, or formingthem with furrows or vrinkles, the occurrence of which would prevent ortend to impede or hinder their perfect closure which is necessary topreclude leakage or bleeding with certainty.

Another aim of the invention is to supply an umbilical hemostat which isso cnstruct ed that there is no danger or likelihood of its becomingunintentionally unclasped or unfastened, which of course, if it couldoccur, would render the appliance unreliable and inadequate for thesatisfactory performance of functions.

A, -urther salient purpose of the invention is the production of aconstricting device of this type which can be easily renderedasepticflvhich can be boiled, and which will not e capal'lle ofabsorbing secretions or the like.

in added object of the invention is to furnish a clamp or ligature ofthis nature which may be quickly and easily applied to the cord or otherpart to be clamped.

An additional feature of the novel ligature resides in the fact that itcan be manufactured economically and sold at such a price that it may bediscarded after having been once used.

To enable those skilled in this art to have a full and completeunderstanding of the invention and its several benefits and advantages,in the accompanying drawing, forming a part of this specification, andthroughout the several views of which like reference characters havebeen employed to designate the same parts, I have illustrated adesirable and invention.

In this drawing:

Figure l'is a plan view of the ligature in open condition;

Figure 2 is a top edge view of the same in closed or operativecondition;

Figure 3 is a face View of the clamp in its closed state; 7

Figure 4 is a section on line4-4 of Figure 1; and

Fi ure 5 is an end view of the device.

Referring to the several views of this drawing, it will be perceivedthat the ligatureor clamping device is made of a single piece ofsuitable spring wire bent to proper or convenient form for the efficientperformance of the intended functions.

Such piece of metal wire, which may be of steel or other metal unooatedor plated, as may be desired, is bent at 11, forming a small eye or loopin the closed or active condition of the device, to provide a pair ofcompanion or correlated lengths 12 and 18, which, in the unclaspedcondition of the appliance, naturally spring apart and diverge from oneanother, as shown in Figure l, thus facilitating and aiding in theapplication of the ligature to the umbilical cord which is receivedbetween such spreading arms.

The end Or terminal portion of the arm 12 is bent up at 10, then towardthe other end of the device at 14 and substantially parallel to the part12, and then down at 15 to, or if desired, down back of the arm 12,thereby forming a rectangular loop constituting a handle which may beadvan-' tageously employed in applying the ligature and as a guardforthe complementary hook of the other arm described hereinafter.

Such loop or handle stands up in a plane practically or substantially atright-angles to that of the two spring arms 12 and 13, all as is clearlyillustrated.

The corresponding free end of the associated arm 13 is bent to form adownwardly projecting part '16, which joins with preferred embodiment ofthe an outwardly-extended portion 17, which in turn connects with anupwardly-directed section 18 terminating'in a forwardly-disposed hook19, which, in the closed or operative condition of the appliance takesover that part of arm 12 between the sections 10 and 15 and looks orholds theligature in clamping condition.

The sections 16, 17 and 18 form a small handle practically atright-angles to the plane of the spring arms and is of assistance andconvenience in manipulating the ligature.

The hook 19, when catchingthroughthe loop of the other arm, maintainsthe two spring arms in practically parallel relation with capacity forsuflicient fieXure to accommodate themselves to the body clamped orgrasped between them and, when this is an umbilical cord, these two armscompress the same adequately to flatten and seal or close the bloodvessels precluding bleeding or loss of blood or leakage from the stumpof the severed umbilical cord.

In order to close the ligature, the operator makes use of the bentportions of the two arms constituting the handles, and he can readilyengage the hook around or over the wire of the companion member, and theappliance once thus closed and locked is safe against accidentalunfastening, the ligature being employed with the assurance that, oncehavingbeen properly applied, there will be no danger or possibility ofunintentional displacement or removal.

An understanding of the construction and modeoii operation o'tthisdevice will these may be varied more or less without departure from theheart and essence of the invention, as defined by the appended claim,and w thout the sacrlfice of any of its substantial benefits andadvantages.

I claim:

An umbilical ligature formed of a single piece of spring Wire bent toprovide two clan'iping sections tending to separate at their free ends,the end portion of one of said sections being bent up, rearwar'dly andthen downwardly to form a loop handle at substantially right-angles tothe plane of said sections, the end portion of the companion sectionbeing bent downwardly, then forwardly lengthwise the section, thenupwardly and then laterally away from the loop or" the other section inhook form, said hook in the closed condition of the ligature taking overthe other section through said loop handle.

7 in Witness whereof I have hereunto set my hand and seal.
